The design and fabrication of an 8-ch, 500GHz-spacing arrayed waveguide grating on (Pb,La)(Zr,Ti)O3 has been successfully achieved for the first time. An insertion loss of 22.1dB, including a 10dB coupling loss, and an adjacent crosstalk of -23.1dB have been obtained. The device is expected to be monolithically integrated into high-speed optical switches to form integrated chips such as a reconfigurable add-drop multiplexer.
